Zusatz zum Patent 816Addendum to patent 816

Im Hauptpatent, dem Patent 8i6 907, ist eine Antriebsanordnung bei Magnettongeräten, die mit bandförmigen Magnetogrammträgern arbeiten, welche beim Betrieb von einer Gummiandruckrolle an die Antriebsrolle gedrückt werden, beschrieben, die dadurch gekennzeichnet ist, daß die Gummiandruckrolle um eine senkrecht zur Antriebsrollenachse liegende Achse so weit klappbar angeordnet ist, daß die Andruckrolle in abgeklapptem Zustand außerhalb des zum Bandeinlegen benötigten Raumes liegt, wobei die Anordnung so ausgebildet sein kann, daß der Tragvorrichtung ein Netzschalter für den Antriebsmotor zugeordnet ist, der beim Klappen der Vorrichtung in die Betriebs- und/oder Ruhestellung betätigt wird.In the main patent, the patent 8i6 907, is a drive arrangement in magnetic recorders with band-shaped magnetogram carriers work, which when operated by a rubber pressure roller are pressed against the drive roller, which is characterized in that the rubber pressure roller arranged so far foldable about an axis lying perpendicular to the drive roller axis is that the pressure roller in the folded-down state outside of the space required to insert the tape lies, wherein the arrangement can be designed so that the support device has a power switch for the drive motor is assigned to the operating and / or rest position when the device is folded is operated.

Gemäß der Erfindung wird diese Anordnung und ihre Bedienung dadurch vereinfacht, daß ein Druckknopfschalter als Netzschalter dient, dessen Bedienungsknopf durch die klappbare Tragvorrichtung bzw. ein Gegenstück an dieser beim Zuklappen in die Einschaltstellung gebracht wird. Beim Aufklappen der Tragvorrichtung wird der Schalter automatisch ausgeschaltet, soweit dies nicht durch l>esondere Mittel verhindert wird.According to the invention, this arrangement and its operation is simplified in that a push-button switch serves as a power switch, the control button of which through the foldable carrying device or a counterpart on this is brought into the on position when it is closed. When unfolding the switch is automatically switched off if this is not due to the carrying device l> special means is prevented.

Um nun das Einlegen des Bandes zu erleichtern, wird der Druckknopfschalter zweckmäßig so an-In order to make it easier to insert the tape, the push-button switch is expediently

geordnet, daß er im wesentlichen unterhalb ■ der Laufwerksplatte liegt und lediglich der Bedienungsknopf durch ein Loch in der Laufwerksplatte tritt, jedoch nur so weit, daß er nur wenig über die Laufwerksplatte herausragt. Zweckmäßig wird auch der obere Teil des Knopfes noch abgerundet, so daß das Band beim Einlegen ohne Schwierigkeiten darüber hinwegrutschen kann.arranged so that it is essentially below the drive plate and only the control button through a hole in the drive plate, but only so far that it is only slightly above the drive plate protrudes. The upper part of the button is also appropriately rounded so that the The tape can slip over it without difficulty when it is inserted.

Diese Ausführung bedingt, daß der Motor stillgesetzt wird, wenn die Klappe mit der Andrückrolle geöffnet wird. Um nun auch bei abgeklapptem Zustand der Tragvorrichtung zu ermöglichen, daß der Motor läuft, ohne daß der Knopf dauernd gedrückt wird, wird gemäß weiterer Ausbildung der Erfindung ein drehbarer Hebel an der Laufwerksplatte derart angeordnet, daß er über das Ende des Knopfes des Druckknopfschalters geschoben werden kann und diesen in der Einschaltstellung festlegt.This version requires that the engine be stopped when the flap is opened with the pressure roller. To now also when folded down State of the support device to allow the engine to run without the button being continuously depressed is, according to a further embodiment of the invention, a rotatable lever on the drive plate arranged so that it is slid over the end of the button of the push button switch and fixes this in the switch-on position.

Wenn jetzt die Klappe wieder geschlossen werden .soll, könnte unter Umständen der Hebel, der ja noch über das Ende des Knopfes geschoben ist, das völlige Schließen der Klappe verhindern bzw. würde beim öffnen der Klappe der Schalter nicht ausgelöst. Aus diesem Grunde ist an der Klappe ein Stift vorgesehen, der beim Zuklappen den drehbaren Hebel wieder zur Seite schiebt, so daß die Klappe bzw. das Gegenstück an der Klappe wieder mit dem Knopf des Druckknopfschalters zusammenwirkt. If the flap should now be closed again, the lever that still is pushed over the end of the button, prevent or prevent the flap from closing completely. the switch would not be triggered when the flap is opened. This is why it is on the flap a pin is provided which pushes the rotatable lever back to the side when it is closed, so that the The flap or the counterpart on the flap interacts again with the button of the push-button switch.

Die Fig. 1 und 2 veranschaulichen ein Ausführungsbeispiel des Gegenstandes der Erfindung. Auf der Laufwerksplatte 1 ist die Tragvorrichtung 2 für die Gummiandruckrolle 3 so angeordnet, daß sie um das Scharnier 4 nach oben geklappt werden kann. Der Magnetkopf ist mit 5, die Antriebsrolle, gegen die das Band 6 im zugeklappten Zustand der Tragvorrichtung 2 von der Gummiandruckrolle gedrückt wird, mit 7 bezeichnet. Unterhalb der Laufwerksplatte 1 ist der Druckknopfschalter befestigt, der aus der federnden Zunge 8, dem von dieser getragenen Druckknopf 9 und der eigentlichen Schaltvorrichtung 10 für einen elektrischen Stromkreis, z. B. den Motorstromkreis, besteht. Der Druckknopf 9 tritt durch eine Bohrung 11 in der Laufwerksplatte ι und ragt etwas über diese hinaus. Der obere Teil des Knopfes ist zur Erleichterung des Einlegens des Bandes 6 abgerundet. An der Klappe ist ein Gegenstück 12 befestigt, das beim Zuklappen auf den Druckknopf 9 drückt und dadurch die Kontakte 13 und 14 schließt. Wenn der Stromkreis auch nach Abklappen der Tragvorrichtung 2 geschlossen werden bzw. geschlossen gehalten werden soll, müßte der Druckknopf 9 solange von Hand gedrückt werden. Um dies zu vermeiden, ist ein auf der Laufwerksplatte 1 um den Punkt 15 drehbarer Hebel 16 vorgesehen, der über das obere Ende des Druckknopfes 9 geschoben werden kann. Wenn jetzt die Klappe wieder geschlossen werden soll, stört, daß der Hebel 16 noch über den Knopf 9 geschoben ist. Es wird daher gemäß weiterer Ausbildung der Erfindung an der Klappe noch ein Stift 17 vorgesehen, der beim Zuklappen in eine Aussparung 18 der Laufwerksplatte τ unterhalb des Hebels 16 eingreift und dabei den Hebel 16 wieder zur Seite schiebt.Figs. 1 and 2 illustrate an embodiment of the subject matter of the invention. On the drive plate 1, the support device 2 is for the rubber pressure roller 3 arranged so that they are folded around the hinge 4 upwards can. The magnetic head is 5, the drive roller against which the tape 6 in the closed state of Carrying device 2 is pressed by the rubber pressure roller, denoted by 7. Below the drive plate 1, the push-button switch is attached, which consists of the resilient tongue 8, the one carried by this Push button 9 and the actual switching device 10 for an electrical circuit, z. B. the motor circuit exists. The push button 9 passes through a hole 11 in the drive plate ι and protrudes a little beyond this. The top of the button is for ease of use Insertion of the tape 6 rounded. A counterpart 12 is attached to the flap, which when closed presses on the push button 9 and thereby the contacts 13 and 14 closes. If the circuit is too after folding down the support device 2 is closed or should be kept closed, the push button 9 would have to be pressed by hand for as long. To avoid this, one is on the Drive plate 1 rotatable about point 15 Lever 16 is provided which can be pushed over the upper end of the push button 9. if Now the flap is to be closed again, bothers the fact that the lever 16 is still pushed over the button 9 is. It is therefore still another embodiment of the invention on the flap Pin 17 is provided, which when folded in a recess 18 of the drive plate τ below the Lever 16 engages and pushes the lever 16 back to the side.
